Driving across the border

On the left, a fun, single-sitting read that was in Dad's library. On the right, a bumper retro celebration of an RPG tome that'll definitely take multiple sittings to ingest...although, I am halfway through already. Both played in and DM-ed B1 back in the day. B2 I only experienced as a player. Am tempted to solo a stack of pregens through the 5E updates, using a homebrew system for randomising character behaviour, etc.
